DropDownList: possible to add new rows after the DataSource has been set?

[Jim Bancroft]

Hi everyone,

I'm have a DropDownList that populates itself from a DataTable. Is
there some way to "append" additional rows after the datasource has been
attached? For example, I'd like to bind my DropDown, then add an extra row
for a default entry that'll appear no matter what data is retrieved.

I've looked around but didn't see an Add() method I could use. Is what
I'm asking possible, or is it the case you're out of luck after binding your
datasource? Thanks for the help.

What you want is easy.. and there definately is an Add() method.

With this you add an item which will end up in the bottom of the list:
DropDownList1.Items.Add("Select an item")

Wíth this you will insert an item in the top (index 0):
DropDownList1.Items.Insert(0,"Select an item")

OR...if you need to create an item that also has a value, since most Items
you have in a dropdownbox should return a value instead of a text.
DropDownList1.Items.Insert(0, New ListItem("Select an item", "VALUE"))

Questions?

Best regards/

Jim,

In situations like yours I add rows to the DataTable after filling in with
data from the database. Then I bind the list to the table in a regular way.
